Population |
consists of all individuals of a species that live together in one place at one time |
|
|
Population Density |
the number of individuals that live in a given area |
|
|
Population Model |
a hypothetical population that attempts to exhibit the key characteristics of a real population |
|
|
Carrying Capacity |
population size that an environment can sustain |
|
|
Logistic Model |
population model in which exponential growth is limited by the density-dependent factor |
|
|
r-strategists |
species that grow exponentially when environmental conditions allow them to reproduce |
|
|
Population Size |
the number of individuals in a population |
|
|
Dispersion |
third feature of a population is the way of individuals of the population are arranged in space |
|
|
Exponential Growth Curve |
a curve in which the rate of population growth stays the same, as a result the population size increases steadily |
|
|
Density-Independent Factor |
a variable that affects a population regardless of the population density, such as climate |
|
|
Density-Dependent Factor |
a variable affected by the number of organisms present in a given area |
|
|
k-strategists |
species that population density is usually near the carrying capacity of their environment |
